5 Claims.

This invention relates to foot wear and has particular reference toheels.

One of the objects of my invention is to provide a detachable top liftfor a shoe heel which 5 may be quickly positioned on a leather, woodenor other well known type of heel without special tools or instruments.

Another object of my invention is to provide a heel top lift which isnot only detachable and permits readily replacement of a new one, but isalso interchangeable with the top lift of the other shoe in order toprovide even wear upon the top lifts.

Still another object of my invention is to provide a detachable heel toplift of the type shown by Patent #1,409,431, but of such structure thatit can be secured directly to the heel, without an intermediate securingmeans, by a simple drilling operation and thus but slightly increasingthe cost of the shoe.

Further objects of the invention reside in the means for preventingrelative rotation of the parts and the manner in which the top lift issecured to the heel.

With these and other objects which will appear as the descriptionproceeds, my invention resides in the combination and arrangement ofparts hereinafter described and set forth in the claims.

In the accompanying drawing wherein two convenient embodiments of myinvention are set forth.

Fig. 1 is a longitudinal cross sectional view of a heel to which myinvention is applied.

Fig. 2 is a view, similar to Fig. 1, of a modified embodiment of myinvention.

Fig. 3 is a partial cross sectional view of the heel with the top liftremoved.

Fig. 4 is a bottom view of the heel with the top lift removed.

Fig. 5 is a side view of the top lift.

Fig. 6 is a top view of the top lift.

In Fig. 1, reference character 1 designates the main body of the heel,preferably formed of wood v, or the like secured to the shoe 2 in theusual manner. 3 is the top lift which has secured thereto a circularplate 4 by means of some suitable fastening means such as nails 5. Thecircular plate 4 which is located in a similarly shaped drilled recess10 in the assembly contains a centrally located threaded aperture intowhich a pin 6 is threadedly engaged. A drilled hole 7 of substantiallythe same diameter as the pin 6, extends through the main heel body 1 andalso through the inside of the shoe and receives the pin 6 to hold thetop lift to the main heel body by frictional engagement. Altho inpractice it has not been found necessary, the hole '7 may be providedwith a soft metal sleeve to increase the frictionalvengagement with thepin 6.

To remove the top lift 3 from the heel 1 it is 60 only necessary toinsert a nail or the like of slightly less diameter than the pin 6 intothe hole 7 and drive the pin 6 outof the hole 7.

To prevent the rotation of the top lift 3 relative to the main heel body1, a dowel like joint is provided which consists of one or more,preferably two, pins 8 which are driven, screwed or fitted into the heelportion 1 in such a manner that a substantial segment of the pins 8extends out into the plate receiving recess 10. Corresponding to thelocation of the pins 8 relative to the plate 4 when the top lift iscorrectly inserted in the heel 1 and the extent that the segments of thepins 8 extend out into the recess 10, pin receiving channels 9 aredrilled in the periphery of the circular plate 4. It will be obviousthat with this type of rotation preventing means that the maximumleverage the plate is susceptible of is utilized; that the plate 4 canbe more readily seated in the recess that if the pins 8 were whollywithin the recess and the plate 4 was provided with pin receiving holes;and the size of the plate and recess can be materially reduced and yetprovide the same lever arm provided by a larger plate with pin receivingholes.

As shown in Fig. 2, the general arrangement of parts is substantiallythe same as disclosed in Fig. 1, with the exception that the frictionpin 6 has been supplemented by a screw 6 which 0' is inserted from theinside of the shoe 2 into the hole 7' extending through the heel 1 andthreadedly engaged with the threaded aperture of the plate 4 which issecured to the top lift 3 by fastening means 5; the screw 6' holding theassembly together.

From the foregoing it will be seen that I have provided simple means forsecuring a detachable top lift to a main heel body in which the heelbody is prepared to receive the top lift by a simple drilling operationproviding a hole longitudinally of the heel and a recess in the face ofthe heel which abuts the top lift, the hole and recess having coincidentcenters.

Having thus described my invention it will be seen that changes andmodifications may be made therein by those skilled in the art Withoutdeparting from the spirit and scope of the invention and I do not wishto be limited to the details disclosed, but what I claim is: 1

1. In a heel, the combination with the main body having an aperturetherein, of a detachable top lift having a plate secured theretoprovided with a threaded aperture, a threaded fastening means positionedin said body aperture and engaging said threaded aperture to secure saidlift to said body, said body having a recess of a shape and depth toreceive said plate, a locking pin secured in said body and located inthe periphery of said recess and a channel in the periphery of saidplate coacting with said pin to prevent relative movement of said bodyand said lift.

2. In a heel, the combination with the main body having an aperturetherein, of a detachable top lift having fastener receiving meanssecured thereto, a fastening member located in said body aperture andcoacting with said means to secure said lift to said body, said bodyhaving a recess to receive said means, and locking means directlysecured in the periphery of said recess and coacting with said firstmentioned means to prevent relative rotation between said body and saidlift.

3. In a heel, the combination with the main body having an aperturetherein, of a detachable top lift having fastener receiving meanssecured thereto, a fastening member located in said body aperture andcoastin with said means to secure said lift to said body, saidbodyhaving a recess to receive said means, locking means consisting of pinand channel members located in the peripheries of said recess and saidfirst mentioned means coasting to prevent relative rotation between saidbody and said lift.

l. In a heel, the combination with the main body, of a detachable toplift having a circular plate secured thereto, said body having acircular recess of a shape and depth to receive said plate, means todetachably secure said plate and lift to said body, a locking pinsecured in said body and located in the periphery of said recess and achannel in the periphery of said plate coacting with said pin to preventrelative movement between said body and said lift.

5..In a heel, the combination with the main body having a circularaperture therein, of a fiat top lift having a fiat cylindrical platesecured to one side thereof, a fastening member located in said bodyaperture directly connected to said plate to removably secure said liftto said body, said body having a circular recess concentric with saidaperture to receivesaid plate, pins located in said recess and directlysecured in said body, and openings in said plate receiving said pins toprevent relative rotation between said body and said lift.
